My first time

This happened later in my life when I was 24. I was out of town working staying in a travel trailer. One day while I was at work a dog showed up. A little under fed but you could tell he was abandoned. I fed him the rest of the day and gave him water. I had made up my mind that if he was there by the end of the day I was bringing him home with me. He followed me around the rest of the day. Sure enough come quitting time he was still there so I loaded him up and drove home. Upon arriving at the house I bathed him. As I was bathing his underside I noticed his red rocket was sticking out a inch. I stopped for a second admired the shape of it then went about my business. After I dried him I let him out and he went and jumped on the couch. Smelling of wet dog I decided to shower. Not feeling like getting dressed i decide to sit on the chair naked. When i did the dog got up for me to let him. So as I was sitting there watching tv petting him I felt his cold wet nose bury into my privates. I pushed him away and he jumped up trying to jump my leg. So I pushed him off and let him outside. I sat back down watching tv thinking about it feeling my dick starting to throbb I thought maybe I'll let him back in. When I opened the door he darted back in automatically went to licking my crouch his big warm tounge felt fantastic. So I decided to spin around slightly bet over with my cheeks spread feeling his tounge run up my ass crack had my dripping out of my throbbing cock. I couldnt take it anymore I hit my knees and planted my face in the mattress I had laying on the floor he immediately mounted me thrusting away. Hitting every spot but the one I wanted him to. I'm moving my hips with his wild stand trying to help line him up then suddenly i felt his tip go in. And with that he thrust all his doggie dick in my humping wildly. I could feel myself building to an organism with every thrust that's when I felt his knot lock into me. The pain was immense but the pleasure was so much more I exploded all over the side of the mattress as I felt the warm doggie jiz filling my insides. He just stood the stuck in me. I loved the feeling on his dick throbbing inside me for the next 2o mins. When he finally freed he locked us both clean and I collapsed passing out in the our cum. Legs spread wide. I was woke later to the feeling of his tounge licking my hole later that night. So I lifted my hips readjusting my self and let him have me again
